Instead he suggested we all watch a movie over drinks. We managed about fifteen minutes of a bad drag queen film and he and Princess agreed it was the worst thing they’d watched since the first instalment of Fifty Shades of Grey last summer.

So in perfect (slightly tipsy) logic we decided to watch the second Fifty Shades film to see if it had improved at all. Spoiler alert: it hadn’t. In fact it’s possibly even less sexy than the books as even the masked ball scene that was moderately erotic in the novel ended up being flat and dull on screen.

The only bit we all approved of was a split second with a spreader bar where Mr Grey finally did something even remotely dominant but again we were surprised by just how non kinky Fifty Shades really is.

The film was either shorter than I imagined or we distracted ourselves with mocking it because it seemed to be over quite quickly and my Master rewarded us for our efforts by putting The Rocky Horror Picture Show on again since we’re all fans of men in stockings.

Princess was sitting in between my Master and I as we watched the film and I’m not sure when I noticed his hand had started to move along her bare leg. Maybe when I felt her squirm slightly against me, growing in intensity as Sir’s hand moved closer and closer to her cunt before he slipped her panties off and slipped his fingers inside her.

She slid down the sofa to allow herself to grind against his thumb on her clit and he ordered me to play with her cunt along with him and kiss him as I did. Princess nearly slipped off the sofa in pleasure as she came round both our hands.

Sir took advantage of her position to push her onto the floor on her hands and knees and strip her bare, pushing her face into my now glorious wet and naked cunt as he fucked her from behind. To show Mr Grey just how it’s done, he began spanking her ass so I could hear each slap on her bare skin and then feel her push further into my cunt as she felt each hard fast spank connect with her.

Princess has a particularly perfect ass for putting up in the air while on her hands and knees and for spanking. The sound of a hand or toy slapping against her skin sounds spectacular and goes straight to my cunt every time I hear it.

It was clearly having a similar effect on my Master because I’ve never heard him spank her so hard. The last slap across her ass before I came round her tongue was so hard and loud it actually echoed round the room and jerked her whole body forward and off my my Master’s cock.

He used the break to sit on the sofa and pull me onto his cock astride him and make me fuck him as he sat perfectly still and pulled my top down so my tits were exposed and easy to see jiggling with the effort of me pushing down deeply as I fucked him as greedily as possible while Princess watched and kissed him and they both took turns to play with my tits.

As soon as I’d made myself come with my Master’s cock , he pushed me off his lap and face first into Princess’s cunt with my ass up in the air. As soon as he started fucking me again, it was my turn to get spanked incredibly hard and the sound and motion of it sent me into that blissed out subspace where nothing except pleasure really matters to me.

I was completely focused on the playing with Princess’s clit and feeling my Master’s cock inside me as he pulled me against him hard enough to actually pop the boning in my waist trainer. It was only when he groaned as he came inside me that I noticed the film was still playing in the background.

He lay back and watched me lick Princess to a last orgasm just as Susan Sarandon asked us to ‘touch-a touch-a touch-a touch me’ and I was reminded what a kinky classic Frank n Furter really is…
